Antilock brake system (ABS)Read and observe
and on page 154 first.
ABS prevents the wheels locking when braking. Thereby, it helps the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pres-
sure on the brake pedal.
Traction Control System (ASR)
Fig. 147
ASR button
Read and observe and on page 154 first.
If the wheels are slipping, the ASR system adapts the engine speed to the con- ditions of the road surface. The ASR makes it much easier to start off, acceler-
ate and climb steep hills even if the conditions of the road surface are unfav-
ourable.
The ASR function is automatically activated each time the ignition is switched
on.
If your vehicle is fitted with the ESC system, the ASR is integrated into the ESC
system » page 154 .
During an intervention of the system, the ASR warning light flashes in the
instrument cluster.
The ASR should normally always be enabled. The system should be deactiva-
ted only in the following situations, for example.
› When driving with snow chains.
› When driving in deep snow or on a very loose surface.
› When “rocking a car free” when it has become stuck.
The ASR can be deactivated via the
» Fig. 147 symbol button.
The
warning light illuminates in the instrument cluster when the ASR is de-
activated.
Ensure the ASR is activated again afterwards.
Electronic Differential Lock (EDL)
Read and observe
and on page 154 first.
If one of the wheels starts to spin, the EDL system brakes the spinning wheel
and transfers the driving force to the other wheels. This ensures the stability
of the vehicle and a quick journey.
The EDL switches off automatically in order to avoid excessive heat generation
in the disc brake of the wheel being braked. The vehicle can continue to be
driven and has the same characteristics as a vehicle not fitted with EDL. The
EDL switches on again automatically as soon as the brake has cooled down.
Driver Steering Recommendation (DSR)
Read and observe
and on page 154 first.
In critical situations, the DSR provides the driver with a steering recommenda-tion in order to stabilise the vehicle. The DSR is activated, for example, on the
right and left vehicle side when braking sharply on different road surfaces.
Hydraulic Brake Assist (HBA)
Read and observe
and on page 154 first.
HBA increases the braking effect and helps to shorten the braking distance.The HBA is activated by very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is re-
leased.

The parking aid (referred to below solely as system) only works when the igni-
tion is switched on.
The system supports the driver via audible signals, via the display on the radio
or via the factory-installed navigation system when parking and manoeu-
vring » Radio user guide, Navigation system user guide.
The system uses ultrasound waves to calculate the distance between the
bumper and an obstacle. The ultrasound sensors are located on the front/rear
bumper.

Applies only for vehicles with 12 sensors.
The interval between the acoustic signals becomes shorter as the clearance is
reduced. A continuous tone sounds from a distance of approx. 30 cm - danger
area. From this moment on do not continue driving!
The length of the vehicle can be increased with an installed detachable towing
device. The danger area thus begins at a distance of around 35 cm on vehicles equipped with a factory fitted towing device.
Towing a trailer
On vehicles equipped with a factory fitted towing device, only system areas A

Activation/deactivation
Read and observe
and on page 156 first.
The system is automatically activated by selecting reverse gear or pressing
the symbol button
» Fig. 148 on page 157 . The symbol
illuminates in the
button; activation is confirmed by a brief acoustic signal.
The system is deactivated by moving out of reverse gear, either by pressing the symbol button or automatically at a speed exceeding 10 km/h (the sym-
bol in the button goes out).
On vehicles which only have rear sensors , the system can only be deactivated
by moving out of reverse gear.

Park Assist (in the following referred to as the system) helps drivers park in
suitable parallel and perpendicular parking places and also to manoeuvre out
of parallel parking spaces.
The system takes over the steering movements when parking or driving out of
the parking space, the driver operates the pedals as well as the gear lever.
The state in which the steering wheel is operated by the system, is referred to
as parking operation.
157Assist systems
The parking aid is part of the park assist system, therefore the information
and safety guidelines » page 156 , Parking aid must also be read and ob-
served.WARNING■ The system only serves as an assistance and does not relieve the driver
of the responsibility for the vehicle operation.■
During the parking process, the system automatically performs rapid
steering movements. While it is doing so, do not place your hands between
the steering wheel spokes – risk of injury!
■
During a parking manoeuvre on loose or slippery surfaces (gravel, snow,
ice, etc.) you may stray from the calculated road because of the surface
conditions. Therefore we suggest that you do not use the system in such
situations.
■
External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people to not be recog-
nised by the system.
CAUTION
■ If other vehicles are parked behind the kerb or on it, the system can also
guide your vehicle beyond the kerb or onto it. Ensure that the wheels or the
wheel rims of your vehicle are not damaged and if necessary intervene in time.■
Under certain circumstances, surfaces or structures of certain objects such
as wire mesh fences or powder snow cannot be recognised by the system.
■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures etc.), the system function may be limited - “incorrect recog-
nition of obstacle”.
CAUTION
The correct evaluation of the parking space and the parking procedure de-
pends on the circumference of the wheels on the vehicle.■
The system only works correctly if the vehicle is fitted with the wheel size
approved by the manufacturer.
■
Do without the use of the system if snow chains or a spare wheel is moun-
ted.
■
If wheels other than those approved by the manufacturer are mounted, the
resulting position of the vehicle in the parking space can differ slightly. This
can be avoided by readjusting the system at a specialist garage.
Note
We recommend performing the parking at a safe speed to about 5 km / h.Functioning

Fatigue detection (break recommendation)
Introduction
This chapter contains information on the following subjects:
Function
165
Information messages
165WARNING■ For the driving ability is always the driver's responsibility. Never drive if
you feel tired.■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The fatigue detection system is designed primarily for motorway driving.
Function
Read and observe
on page 165 first.
The fatigue detection system advises the driver on the basis of information
about the steering behaviour, to take a break from driving. The system recom-
mends a break at speeds of 65-200 km/h.
After the ignition has been switched on, the system evaluates the steering be-
haviour for 15 minutes. This baseline analysis is constantly compared with the
current steering behaviour.
If the system detects deviations from normal steering behaviour due to possi-
ble fatigue of the driver, it recommends taking a break from driving.
The system deletes the stored baseline analysis if one of the following con-
ditions is met.
› The vehicle is stopped and the ignition switched off.
› The vehicle is stopped, the seat belt removed and the driver's door opened.
› The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
Activation/deactivation
The system can be activated/deactivated via the MAXI DOT display in the As-
sistants menu option » page 47.
Information messages
Read and observe
on page 165 first.
In MAXI DOT display the icon appears for a few seconds and the following
message.
Fatigue detected. Take a break!
An audible signal is also emitted.
Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Save tyre pressure values
166
The tyre pressure monitoring function (hereinafter referred to only as a sys-
tem) monitors the tyre pressure while driving.
If the rolling circumference of a wheel is changed, the warning light in the
instrument cluster illuminates and an audible signal sounds.
Information on the procedure for the notification of change of tyre inflation
pressure » page 40 .
The system can only function properly if the tyres have the prescribed inflation
pressure and this pressure values are stored in the system.
WARNING■ Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 198.■
The system cannot warn in case of very rapid loss of tyre pressure, e.g. in
the event of a sudden puncture.
